i wanna emphasize this observation. when cbi ron was first seen in the series... season 1 episode 7. he was focused with that creepy sound playing similar to the one we always hear whenever we see the red john smiley face painted on the walls... co incidence? go back to that episode and youll see what i mean.

and how come that none of that none seven suspects were introduced in the series with that red john creepy sound?
